C# - Fetch Website Source Based On Client Computer Rather Than Server In ASP.NET?
Mar 21, 2012
I am using the following code to fetch html source website.
private string Extract_Source(string url)
{
string output = "";
System.Net.HttpWebRequest req = (System.Net.HttpWebRequest)System.Net.HttpWebRequest.Create(url);
[code]....
It can fetch source properly but the problem is it fetch website source based on server from where script executed (i mean where website hosted), but i want to fetch content based on client information (ip etc)

I want to make an application that can push ads (website) to client..
Here is the case : Client try to connect to internet via wifi. Once the client is connected, server send a website address to client, and a popup (website sent by server) will appear in the client's computer in default browser.
I can list all IP connected to server, but i don't know how to push the website to client
Here is the code to list all IP connected to server : (import System.Net library)
String strHostName = "";
if(args == null || args.Length == 0){
strHostName = Dns.GetHostName();
[Code]....

I wrote a program in VB2005. It is a program that is supposed to run in a client computer accessing an MS Access .mdb file stored in the server. The program itself is stored and run in the clients computer. I am not good in networking at all. The way I do it now is:
1. Have a directory made in the server to hold the MS Access .mdb file, and have the directory to be shared.
2. Have the same directory accessed and mapped in the client computer (say to Z:)
3. Then have the program in the client computer simply access the database as if it is in the same computer (as the directory already mapped into the client computer). In the VB 2005, this is done when we set the connection string of the database connection.
However, my user is complaining that by doing so, the database is basically exposed to the operator of the client computer (through the mapped directory), hence more vunerable for any bad intentions from persons who may have access to the client computer but not the server. He insists that he used to have a program that does exactly the same thing like my program, but the database is shielded in the server, where it cannot be seen in the client computer (I have other people who confirm that this can be done, though they can't tell me how, since they are not programmers themselves). Now, I have no idea on how to connect a database that way, and I don't even know where to start looking.

I am trying to create an application for official use. The idea is to built in the Chat communication. I am wrtting some code for Chat Server/client.
1) Where do I keep the DB (suppose if I have SQL server on hosted web site)
2) Can I configure DB on my home PC ( no matter where client runs throughout the world if should refer the DB on my machine)
3) For Server - How to read the Users(Name and IP) from domain(AD) as well as on LAN.

how to create a client/server... But I couldn't... I don't want anything fancy. Just want the client to send the server 4 numbers, depending on the user's choice; after that, the server would turn off the pc, restart it, etc. It all depends on the number received. Is there a rather "simple" way to do it? If it's not to much trouble you could use Atheist's example. (Btw I don't understand the code and, yes, I've checked on [URL])

Hey guys, I am trying to send data from client to server (encrypted) and the string sent from the client is not the same as recieved from the server. I've been killing my brain for hours to get this to work but I cant manage. Im converting everything to Base64 string.
Client:
Public Sub SendMessage(ByVal msg As String)
Try
SyncLock myclient.GetStream
sw = New IO.StreamWriter(myclient.GetStream)

We are creating a Who wants to be a millionaire style game in VB. Our server is pulling information such as questions and answers from a Access Database and sending them to the contestants (Clients). All transfer of information is directly from the server to each client. One of the "Life Lines" we want to use is "Ask a friend", where one client is able to Instant message another client for a short time to get help on the question.

I've basically made a basic tcp server/client application. The thing is that I'm behind a router and so will be the other people that use my clients. I've had to use port-forwarding or the software "rinetd"to run quite a few applications online.
Let me explain: I'm on a lan network that connects to the internet. Whenever I want to host a server - for instance a basic ftp or http server. If I give my external IP to anyone, they won't be able to access my server. Even if I portforward, it doesnt work. I have to use rinetd here. For other applications, portforwarding works. I'm not sure how these things work at all.
Anyway, my issue now is that I have created this server/client application. I'm having serious doubts that if I run the server, I'll have to either a) portforward or use rinetd to get people to connect to my server. IF I need to portforward, that's fine. However, using rinetd would really suck... My 2nd concern is as follows: IF the person running the client is in a similar situation as me (i.e he's on a lan that has a router which connects to the net), will he have to portforward or use rinetd as well? If he portforwards that's fine. But I don't think I could get people to use rinetd.... Also, if there are more than 1 person on a lan trying to connect to my server, there is a big problem when they try to portforward: they will only be able to allocate one of their internal ip to that port, and the others won't be able to connect, right? How does this work? I mean, I use many softwares like msn/skype/(some games)/firefox that do not need portforwarding/rinetd. Yet they work. My housemates(other people on the lan) use the same softwares, and it works fine. There's no clash/probs watsoever How come these run fine?
Anyway, back to my issues. Given I have no knowledge about how the above work, I was wondering whether there was a way to host a vb .net server application on an external website (external to my house) so that I might *avoid* the above mentioned problems, and to what extent that would be a sound solution.

I have been reading through Atheists posts in regards to client-server and TCP client/server connection's. But how do i go about writing a program with 1 client and server where the client side creates a text file.Once the server sees there is a text file it connects and downloads it to itself or the client pushes the text file to the server.Once on the server i will read the text file and put its info into a sql db.

Im using the code from [URL] as a starter, most of the code is the same. the chat system works fine but on the client a added a disconnect button "clientSocket.Close()" and as soon as i click that i get errors, on the client, this is the code...
Private Sub getMessage()
For infiniteCounter = 1 To 2
[CODE]...
And this line...
serverStream.Read(inStream, 0, buffSize)
gives me "Unable to read data from the transport connection: A blocking operation was interrupted by a call to WSACancelBlockingCall."
Now im talking the server, after the client clicks disconnect or closes by task manager, looses connection, etc the server crashes and gives me.

Well to get started on my program I'm working on a program that downloads info form World of Warcraft Armory website and then gives you statistics about random stuff. I'm having a little trouble with getting the XML. When you right click and click View Page Source you get the XML document. That is the exact text i want in my textbox of my form. So to recap: I want to get the "View Page Source" code of the website posted above. Iv tried the .documenttext and the .gethtml and .inner .outer ext ext but it all returns HTML and not the XML document from the right click and "View Page Source"

So I grab a source from an url in vb, and as expected it lists everything written in there. My interest lies in the info that resides outside of the tags in the code. And that stuff gets updated daily, so they're not static strings eitherm here, I've been able to filter out all the tags, and grab everything outside them, and show em in a messagebox, but somehow it picks up every line change, that's essentially an empty character, and lists those as well. We hit our heads together with a couple of friends but we couldn't work out why.Also, I've tried modifying it to find different stuff, but somehow everytime I try something different the system gets screwed up and it finds no results. But that's just because I'm such a buffoon with the code.

How can I show a website source code without the use of web browser. I only need the source code, i don't want to see the images or any other things.
More Info:Just like when you go to a website and if you are using Firefox you click CTRL+U and it will show you the page source code.
I want to read specific information from a website, but i don't want to the website to take longer on loading. (Because of Images)

I wrote a VB code to call a sp in sql server 2005, which returns a recordset as follows:Dim objRecordset As ADODB.Recordset Set objComm = New ADODB.Command
Set objRecordset = objComm.Execute If Not objRecordset.BOF And Not objRecordset.EOF Then
Set objRecordset = objRecordset.NextRecordset I need to continue to get next recordset since there are many select statements inside the sp which I need to get the data. The code works fine when I create the DSN using SQL Server but it does not work when using the connection string or SQL Server Native Client DSN. It either breaks at Set objRecordset = objComm.Execute ( connection string )or at If Not objRecordset.BOF And Not objRecordset.EOF Then(SQL native client )
I have worked on this for a couple of days now and could not figure it out.Is this a bug in SQL Native Client or something related to some configuration on the database side? IS there a way I can change the connection property to get this working using SQL native client or connection string?
